I think the fact that BJ2 is SO similar to the original is one of its weaknesses, conversely, it is also its biggest strength as well!!! It is very much the same film, with a few sparky new locations! However, it is a format that works....we all know the characters, so no faffing around needed to establish them, its straight in this time.
I heard someone stuffy on breakfast telly this morning saying this film was "an insult to the masses" as its basically the first film wrapped in a slightly jazzier box. Thing is, how gutted would everyone have been, had the format been changed?! It DOES work, and may not be quite as good as the first to some, but its flipping funny and a good 2 hours spent in my opinion!
PS...What DO people see in that Colin Firth bloke? He is so wooden, he makes Hugh Grant appear talented!
